Does Psalm 128 mean that everyone who fears the LORD will have a wife and children? What about someone who doesn't?

The psalm opens wide: "Blessed is everyone who fears the LORD, who walks in his ways" (128:1). Then it speaks to one person, you, and pictures one home: "You will eat the labor of your hands" (128:2), and "Your wife will be as a fruitful vine in the innermost parts of your house, your children like olive shoots around your table" (128:3). It sums up, "Behold, this is how the man who fears the LORD is blessed" (128:4). The psalm doesn't speak of anyone who fears the LORD without a wife or children, and it doesn't say that such a person is outside the blessing of 128:1. Other Scripture speaks of those without sons and daughters. Isaiah 56 has, "Do not let the eunuch say" (Isaiah 56:3), and gives his words, "Behold, I am a dry tree" (Isaiah 56:3). Then the LORD speaks of "the eunuchs who keep my Sabbaths, choose the things that please me, and hold fast to my covenant" (Isaiah 56:4): "I will give them in my house and within my walls a memorial and a name better than of sons and of daughters" (Isaiah 56:5). The psalm before this one says, "Behold, children are a heritage of the LORD" (Psalm 127:3). These notes set the verses side by side, and don't make Psalm 128's picture a promise of any one home, or a measure of anyone's.
